Fontanez had made changes to his entire team after the knockout loss and bounced back for a first round knockout against soft opposition. Quintero was at a crossroads moment having lost his lone title shot in 2012 and every time he stepped up the competition thereafter.

Quintero showed the higher work-rate and was making his way inside as Fontanez fired hard right-hand counters. At the beginning of the fourth round Quintero was making his way inside with ease and blasted Fontanez with a right hand dropping him like a sack of potatoes. Fontanez beat the count only to go down again on a flurry of punches, prompting the corner to throw in the towel.

It was a good performance from Quintero and a harsh dose of reality for Fontanez that now finds himself back at the drawing board.

Following the fight Quintero said “Feels great and extremely satisfying to get this win in the name of my country, it fills me with pride to know that I added a win for Mexico. My left hand was a big weapon for me tonight.” “This victory is for the people of Mexico.”

After the fight Fontanez said “I knew he was a great experienced fighter going into this fight and for that reason I had a very intense training camp. I thought I was ahead on the cards but he landed a lucky left shot. I’m going to go back to Puerto Rico and continue my training.”

From the opening bell the level of polish on each of these fighters was apparent. The movement, speed, power, and fundamentals all favored Morales. Negron had never faced a fighter with a winning record- his last opponent had a Glass-Joe-esque 1-40 record and was taking a major-step-up in competition. Morales’ level of competition up to this point has been the stronger of the two- having only fought two fighters with losing records.

Morales fired his right hand with precision and set traps to counter over Negrons jab. By the end of the second round Morales was becoming more consistent with his attack and it was apparent at the end of the sixth Negron didn’t have an answer for the young Mexican American’s assault.

Mercifully referee Zack Young stepped in for a good stoppage at 2:07 in the seventh round to hand Morales the technical knockout after he landed at least a dozen shots to the head of Negron.

After the fight Morales said “I trained really hard for the fight and I’m proud to get a win for Mexico and this great rivalry. I was able to use my jab and my straight right consistently, that was part of our strategy.”

Negron said “I had seen him fight before on film, I thought he was slower. He surprised me with his speed and kept me at a distance.” “He was too fast with his counter punches.”

In the televised opener of the evening Oscar Negrete 12-0 4KO’s remained unbeaten- defeating Jose Estrella 14-8-1 10KOs by technical knockout at the end of the sixth round with sharp and quick lead right hands and fast combinations. Estrella’s corner decided he had enough and advised referee Jack Reiss to stop the fight.

Negrete looked good again, the young Colombian Olympian- trained by Jose Santa Cruz, father of Leo Santa Cruz has good upside in a division that promoter Golden Boy could keep him busy with competitive fights with little to no political limitations blocking bigger fights in the future.

Negrete said after the fight “My strategy was to box early on and wear him down for a late round knockout. My straight right was a really effective weapon against him because he would stand straight up. I hope to fight once or twice more, then fight for a title.”

Hector Tanajara 2-0 1KO of San Antonio won a unanimous decision over Antonio Martinez 3-5 3KOs of Durango, Mexico. Tanajara- who is trained by Robert Garcia had a good outing but, pulls straight back a bit and showed he tends to be slow to return fire when he wasn’t first to initiate the action. Tanajara will undoubtedly correct any early holes and still has good talent with solid form in his punches and footwork.

After the fight Tanajara said “I felt in control thorough-out the fight my jab was one of my more effective weapons when I used it- had I used it more it would have been a shorter night.”

Pacoima product Emilio Sanchez 10-0 7KO won a technical knockout over Juan Sandoval 7-17-1 4KOs as the doctor called a halt in between rounds three and four due to a badly swollen right eye. Sanchez was handily winning the fight before the appropriate stoppage. After the fight Sanchez said “our strategy was to break him down to the body throwing combinations and keeping up a good pace, I felt comfortable and liked the improvements that I made.”

Francisco Esparza 1-0 won his pro debut via unanimous decision over Carlos Gonzalez on scores of 40-36 by all three judges. Gonzalez’s woeful record doesn’t indicate the fact that he can come in and give a young fighter problems, he’s tough as nails but is out-quicked and out-boxed making him a perfect pro debut opponent. Esparza showed the tools to get it done.

Opening the nights action Oscar Duarte 3-0-1 2KOs won a split decision over Alejandro Salinas 3-1 3KOs in the battle of the briefly undefeated on scores of 38-37 twice for Duarte and 38-37 for Salinas. Duarte dropped Salinas in the second round with a right hand that opened a gap on the card too hard to overcome in a four round bout.

In an action fight against his fiercest pro opponent yet, Jose Ramirez rose to the occasion and claimed a vacant junior welterweight belt Saturday night, outpointing Amir Imam by unanimous decision in the Top Rank ESPN main event.

Oleksandr "The Nail" Gvozdyk spent most of the fight with Mehdi Amar nailing him with an assortment of combinations to claim a vacant interim light heavyweight world title, and Michael Conlan scored an impressive KO victory to stay unbeaten.
